Prepare one package of red sugar free jello and pour into an 8 or 9 inch square glass baking dish. Let set.

Prepare a package of green sugar free jello and carefully spoon onto the sour cream. Let set.

Cut into squares and serve.

I tried this one Christmas years ago and my family said, "you dope, you are supposed to use whipped cream not sour cream!" Nobody ate it but me. It really is quite delicious.

It can also be made in individual serving containers so it is portable and easier to count the calories, fat, carbs.
